Current DAC circuit
86/139
The current DAC has three possible current ranges that can be selected using the
DacRange[1:0] bits in the CurrDacCtrl register. The DAC range selection table is shown in
Table
Table 35.
By changing LSB current value, all steps will change following this relation:
where N is the value of DacValue[5:0] bits.
